Requirements for Sill anchors and ledger boards?

In my neck of the woods, sill plates must be have an anchor bolt within 12" of each corner and opening in the plate (door way), and every six feet in running lengths. Strapping, rafter ties, and general metal framing connections required have a lot of local variations, obviously much more stringent in coastal and siesmic areas, but even if they are not required by your local code, they are very cheap for the amount of structutal integrity they supply, and I highly recommend their generous use. I am not sure exactly what you mean by roof ledger board, so will pass on that one.

Requirements for Sill anchors and ledger boards?

As Troubleseeker mentioned, there are some basic standards in general for attachment locations and points, however, code requirements can and do vary by region, ESPECIALLY by Towns and Cities. Some areas are more particular and may want to see more than (above and beyond) what is required by general building codes.
You need to check with your local building dept. It only takes a phone call to find out what they want to see. Making phone calls to the local building depts is something that contractors do alot - to check on the local code requirements....

All good advice... Just a side note: if you're using acq treated double check that the straps or anchors are stainless or hot dip galvanized and rated for that or they'll be illegal as they will get eaten away. Most places switched all of their hardware over so you cant go wrong but I have seen places still carrying the old stuff and people, not knowing the dif., buy it because it's cheaper.
